(let ((g (prepare-change-group)))
(activate-change-group g)
(insert "b\n")
(insert "c\n")
(cancel-change-group g)))
#+end_src
Adding an explicit `undo-boundary' call before preparing the change
group fixes the problem for me. Should `prepare-change-group' do
something like that implicitly?
Michael.
